Little air bubbles???

[Race2d]

So I have a 46 gallon bow front tank running two marineland hob penguin 350 Bio wheels. I also have a air curtain and a round air wheel and a boat that has a door that goes up when it fills with air. So my question is that the tanks have a lot of little little bubbles in the tanks floating around in the water how do I get rid of them or is this this normal? The tank is cycled with fish in it. And its not the type of bubbles that form when u first fill the tank up. The tank is just not crystal clear IMO. Any feed back would be greatly thankful

Shut off all the air for a bit and see if you still see them. the HOB will cause a few due to the surface tension being broken.

I do and I think it is the hob filter should I add a power head in and point it at the top?
